A further object of the invention is the pro- Vision of a plurality offormers mounted upon one and the same carrier whereby designs of anydesired character may be formed in the Work, each former controlling theformation of a part of the design.

A further object of the invention is the provision of a plurality ofinterchangeable formers, each controlling the formation of part of thedesign and all mounted on the same carrier.

A further ,object of the invention is the pro- Vision of a numberv ofadjustable formers mounted on the same carrier, in virtue of which thecuts on various sizes of articles may be controlled.

My invention comprises additional improvements appliedv to the machineset forth and described in my application filed July 25, 1903, SerialNo. 166,995.

In the accompanying drawings, Figure 1 is a front view of a machineembodying the present improvements.l Fig. 2 is a side view thereoflooking from the right. Fig. 3 is a plan view. Fig. 4 is a section online 4 4 of Fig. 3. Fig. 5 is a perspective View of one of the former orpattern supports. Figs. 6, 7 8, and 9 are views of a modificationhereinafter described.

Like characterss designate similar parts throughout the several views.

Referring to the drawings, the machine is shown comprising side framesl5 and`6, united by tie-rods 7. Y V

Designated by the numeral 8 is a plate which unites the side frames. 5and 6 and is (No model.)

connected thereto by bolts 9, fitted in slots 9', and pivoted to thisplate by a bolt 10 is a knee 11, which is longitudinally grooved at 11for the reception ofv a tongue on a crossslide 12, said tongue beingclamped in position after adjustment by a'gib 13, .actuated by ahand-screw 14, as shown in Figs. 2 and 4.

Constituting a part of the' knee 11 is a substantially circular plate112, which is pivoted on the bolt 1() and is provided with curvedslots'113 for the reception of bolts 15, carrying nuts 16, in virtue ofwhich the plate and the parts supported thereby and hereinafterdescribed may be adjusted on the pivot-bolt 10 and'tlien clamped firmlyin position.

Secured to slide 12 is a plate 17, having a series of apertures 17/, andwhen the screw 14 is loosened said slide 12 may be moved longitudinallyto bring any one of the apertures opposite a spring-actuated stop-pin orplunger 18, as set forth in my application aforesaid.

Attached to the slide 12 by bolts 19 is a plate 20, said bolts fittingin transverse slots in the slide, whereby'a'n angular adjustment of thesame may be obtained, as in my application aforesaid. Plate 2O isprovided with standards 21 22, in which are formed bearings for arock-shaft 23, each end of which carries an arm 24, secured thereto by apin 25 or otherwise, so that the arms will move in unison., A stop 26,rising from a bearing 22, limits the backward movement of said armsby-engagementwith one of them.

Pivoted at 27 to and depending from the upper ends of the arms 24 arelinks 27 27, the lower ends of which are secured to a crossplate 28,pivoted at 29 upon the links, as illustrated in Fig. 2. Bolts 3() passthrough slots 31 of the links and serve to secure the parts togetherwith a capability of adjustment in the arc of a circle.

As illustrated'in Fig. 1, the cross-plate 28 is provided with a bearing32 for the reception of'an arbor 33, the' upper. end of which has a head34, upon which the blanks'35 to be ornamented are secured in any desiredway, and any form of chuck maybe employed for this purpose-for instance,that setforth in my application above mentioned.

For holdingthe arbor 33 and the blank 35 IOO secured thereto againstrotation during each cutting operation an index-plate -36 is provided,said plate being secured to the head 34 in any desired way. Theperiphery of this plate is provided with a series of notches 36corresponding to the spacing of the cuts to be produced in the blank,and these notches are adapted to be engaged by a detent 37, pivoted at37 to the bearing 32, said detent being actuated by a spring 38. Thisdetent is in the form of a lever, and it may be disengaged.

from any of the notches by pressing upon the lower part thereof, as willbe readily understood and as fully set forth in my applicationaforesaid. Designated by 39 is an arbor which is journaled in bearings40 of a head 41, the latter being secured on the frame 5 in the usualmanner. On shaft 39 is a cone-pulley 43, which may be driven at anydesired speed by a belt applied thereto, and also clamped to said shaftis a tool 44, composed in this instance of a number of sections, each ofwhich makes an individual cut in the blank 35. This tool is shown ascomposed of a series of grinding-disks 4, and although these disks areillustrated as clamped tightly together they may be separated, ifdesired, to enable any required space to be made between the cuts.

Designated by 46 `is a slide which may be adjusted back and forth .byscrew 47, and in bearings of this slide is journaled a wide roller 48for cooperation with the former in use, as will be hereinafterdescribed.

`For producing any desired design upon the blank to be cut I employ inthe present instance a series of formers, each of which 4conforms inoutline to the portion of the design which it represents and to bereproduced by the cutting-tool upon the blank, and to afford the savingof time in making the cuts the tool is composed of several implements,all of which act simultaneously upon said blank in producing a series ofgrooves, each of said grooves being a counterpart of that developed uponthe edge of the former in use while any one series is being made, aswill be hereinafter explained. This sectional former is shown moreparticularly in Figs. 3 and 4, is I chine to accommodate blanks ofdifferent sizes or to make shallow or deep cuts in said blanks. Hubs 52are sleeved one above the other upon a spindle 54, and they may all beclamped together by a nut 56, (see Fig. 4,) and by loosening this nutthe formers may be swung around on said spindle to bring the onerequired into position, or they may remain clamped in place and bebrought to the proper location b v indexing' the blank.

Designated by 57 is a toothed wheel secured to the lower end of theformer-carrying spindle 56, and to the lower end of the blankarbor 33 isalso secured a similar toothed wheel 59. To cause the arbors to rotatein unison when one is turned to index the blank and to bring the desiredformer into position opposite the gage wheel or roller 48, anintermediate gear 60 is mounted on a stud 61 in the web uniting thebearings 32 and 32 of the frame 28, said wheel meshing with the gears 57and 59, as illustrated in Fig. 1.

In Figs. 6 to 9 a modification of the manner of supporting the formersis illustrated, and in said modification a head 62 is shown, said headhaving a spindle 63 adapted to be inserted in the socket in the top ofthe shaft 58, said spindle being clamped in position by a screw 64. Inthis form of the invention formers 65 are shown secured to plates 66,the latter being slotted at 66 for the reception of screws 67 and eachplate having a vertical iiange 662, to which the former is attached byscrews 68. By loosening the screws 67 the plate to which the former issecured may be adjusted to position the former carried thereby properlywith relation to the work to be accomplished. This constructionIprovides a flat base on which the formers are adjustably mounted.

In Fig. 3 the glass to be cut is shown as of irregular contour, and thecomplete design to -be reproduced thereon is represented by thesectional former 49, each section of said former having the outline ofpart of the complete design.

A handle 7 O is secured to the bearing 32 for a purpose hereinafterstated.

ln operation the improved machine works as follows: A blank 35 beingsuitably secured to the spindle and the desired former for the part ofthe design to be cut being in place opposite the roller 48, the tool 44is rotated by a belt applied to the pulley 43, and an operator thengrasps the handle 70 with his right hand and pushes with the other handagainst one of the arms 24, thus bringing the ledge or stop Z1 of thepattern in use into contact with the roller, the position of `which issuch as to permit the tool to just clear the blank. By now swinging' theframe 28 around its trunnions the blank will be rolled in front of vthetool in conformity to the shape of the pattern then in use, and saidtool will cutinto the glass and will again clear it when the ledge orstop a on said former engages the roller 48. By now indexing theblank-arbor 33 until the detent 37 enters the next notch of the plate 36(this action causing the gearing 57, 59, and

60 to be rotated'and to impart a simultaneous indexing movement to theformer 49) a blank is turned to bring a new part thereof opposite thetool, and the operation will then be repeated, the tool making a secondcut in the blank conforming to the part of the design represented by theformer-section then in use, and so on until all the outlines representedby the various formers have been reproduced on the blank. When a designof another kind is required, the former in use is replaced by anotherhaving patterns conforming to said design, and by again changing theseformers it will be seen that any desired ornament may be produced on theblank. Generally a number of cuts are made in producing the multiplerepresentations of each former-blade; but, if desired, saidrepresentations may be made ata single operation.

Any desired cutting, buiiing, or polishing implements may be employed inoperating upon the blank, the invention not being limited to thegrinding-disks shown.

Changes may be made in the form and proportions of `the parts, and theymay be variously arranged in a manner different from that illustratedwithout departure from the invention.

Other means for supporting and indexing the blank may also bey employed,and the invention is not restricted to any specific use, for it may beutilized in various arts.
